Earing measuring instrument Model 126

opticalnon-contactlaboratory

The Ear Measuring Instrument Model 126 Plus-Optic is a stationary device for optical, contactless axial measurement of earing on deep-drawn cups and raw cans. It records the cup edge during one rotation and provides standardized evaluation with exportable protocols.

Overview

• Optical, contactless measurement of earing on deep-drawn cups using an optical sensing unit (Model 126 Plus-Optic); no mechanical chuck required — cups are magnetically attached to the rotary table in the Optic variant.
• Device composition: rotary table and vertical gauge head. For non-optic variants, a jaw chuck centres and fixes the cup.
• Measurement is performed during one rotation of the rotary table while the sensor scans the cup edge; pneumatic versions use a test roller that lowers onto the sample.
• Operation via supplied evaluation software on PC or directly at the device; PC is to be supplied by the customer.

Test principle and results

• The measuring unit detects the cup edge during a single revolution and returns to its home position after measurement to enable quick sample change.
• Output formats: .pdf, .txt, .csv (importable into MS Excel).
• Measurement protocol includes (among others):
• He_(mm) = Average earing height
• He,max (mm) = Maximum earing height
• H_(mm) = Average cup height
• Z(%) = Average earing percentage
• Number of earings
• Date, lot, operator and other protocol metadata
